Abstract
The invention discloses a duct tape and a manufacturing method thereof. Through an extrusion covering process, the duct tape is prepared by covering a first thin film layer on one surface of a base layer, covering a second thin film layer on the other surface of the base layer, coating an isolating agent on the other surface of a first thin film layer, and coating adhesive agent on the other surface of a second thin film layer. The duct tape, through covering the thin films on both surfaces of the base layer, greatly improves binding firmness between gauge and the thin film layer and eliminates a demoulding phenomenon; and meanwhile, the duct tape can avoid a corrugated edge phenomenon due to local relaxation of the gauge, and greatly reduce production cost.
Description
Technical field
The present invention relates to a kind of cloth base adhesive tape and preparation method thereof, relate in particular to a kind of cloth base adhesive tape that is laminated with double-layer films and preparation method thereof.
Background technology
Cloth base adhesive tape is complex as base material with the heat of polyethylene and gauze fiber.Be coated with the high viscosity synthetic glue, and be composited with two-sided separate-type paper.Stronger peeling force, stretching resistance, grease resistance, ageing-resistant, heatproof, waterproof, protection against corrosion are arranged, and are a kind of high adhesive tapes of insulation.Cloth base adhesive tape is mainly used in that carton is sealed, carpet seam is merged, heavy type is tied up, waterproof packing etc.Also frequently use in automobile industry, electromechanical industries at present, be used for the waterproof measures such as automobile cab, cabinet, rack local preferably, be easy to cross cutting processing.
The structure of common cloth base adhesive tape is in the market: first the one side at gauze is laminated with PE film, then at surface coated one deck separant of PE film, another side coating one deck tackiness agent of last gauze.The binding strength of the gauze in the cloth base adhesive tape of this structure and PE film is not good, affects following process.The more sparse gauze of warp and woof particularly, gauze and PE film be laminated with rear with finger gently a stranding stripping phenomenon (being gauze and membrane sepn) will appear, following process is had a negative impact.Situation is serious, also can affect the use properties of finished products of adhesive tapes, as: occur demoulding, rupture of membranes during the adhesive tape uncoiling, adhesive tape is difficult for tear fracture, or the yarn of tape edge deviates to produce the bad phenomenon such as burr during tear fracture.
In addition, because gauze used is mesh structural porous structure, higher Amount of spread must be reached when making gluing and just the hole of gauze can be filled up, adhesive tape will reach good viscosity, and required Amount of spread is higher, be approximately 100 g/ms, simultaneously hot-fusible pressure-sensitive adhesive is take SIS and SBS as material of main part, and this material unit price is higher, so cost is higher.
For the defective of above-mentioned prior art, be badly in need of a kind of brand-new cloth base adhesive tape of invention and preparation method thereof and solve the deficiencies in the prior art.
Summary of the invention
In order to solve the problems of the technologies described above, the invention provides a kind of cloth base adhesive tape and preparation method thereof, the substrate both sides of this cloth base adhesive tape all have been laminated with film.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of cloth base adhesive tape comprises basic unit, is laminated with in the first film layer of basic unit one side and is laminated with the second thin film layer in basic unit's another side, and the another side of the first film layer is coated with one deck separant, and the another side of the second thin film layer is coated with adhesive layer.
As a further improvement on the present invention, the material of described basic unit is the gauze of mesh structural porous structure.
As a further improvement on the present invention, the material of described the first film layer and the second thin film layer is any one in PE, EVA or PP.
As a further improvement on the present invention, the Amount of spread of the adhesive layer of described cloth base adhesive tape is 50～60g/m
2
A kind of making method of cloth base adhesive tape specifically comprises the following steps:
Employing is extruded and is laminated with technique and first is laminated with the first film layer in the one side of basic unit, then is laminated with the second thin film layer at the another side of basic unit, then at another side coating one deck separant of the first film layer, at last at another side coating one deck tackiness agent of the second thin film layer.
The present invention compared with prior art has following beneficial effect:
After cloth base adhesive tape provided by the invention and preparation method thereof all is laminated with the last layer film by the two sides in basic unit, make the binding strength of gauze and thin film layer greatly promote, eliminated the phenomenon of demoulding, simultaneously can be because the flounce phenomenon appear in the gauze partial relaxation, and reduced production cost.
